Phospholipid metabolism; phosphatidylcholine biosynthesis; phosphatidylcholine from phosphocholine: step 1/2.
Belongs to the cytidylyltransferase family.
The serine residues of the C-terminus are phosphorylated. The inactive soluble form is stabilized by phosphorylation, the active membrane bound form is promoted by anionic lipids or diacylglycerol, and is stabilized by dephosphorylation.
Cytoplasm > cytosol. Membrane. It can interconvert between an inactive cytosolic form and an active membrane-bound form.
